Title: A braking system for a motor vehicle
Inventor: SCHMIDT GUENTHER
IPC: B60T8/92
Filed: 1991-02-15
Abstract: In a braking system for a vehicle having at least two brake pressure lines (4, 6) between a master brake cylinder (1) and having wheel brake cylinders (5, 7, 8) skid inlet valves (9, 10, 11) bypassed by return pump circuits (16, 24) the inlet valve(s) (9) for the rear wheels is (are) closed in its (their) normal deenergised state and is (are) opened by a control device (36), eg in a pulsewise manner, to effect braking. The control device (36) may have a computer which calculates the optimum rear axle pressure on the basis of signals from wheel sensors (34), pressure sensors (38, 39), a pedal sensor (41) and a load sensor and compares the actual and desired pressures. It may also respond to a sensed low fluid level. There may be provided a pressure valve with a non-return valve in a bypass to the pulsed valve (9) to supply the brakes in the event of failure of the latter. The pressure valve may be actuated by the pressure of the wheel cylinders or the pressure downstream of a throttle (17). <IMAGE>

Title: Ac motor control system
Inventor: LLOYD SYDNEY
IPC: H02P6/08
Filed: 1991-05-24
Abstract: The angular position of the shaft of a three-phase induction motor 11 is controlled by energising the induction motor from a cycloconverter 1 and suitably changing the polarity of the phase-sequence of the output 8, 9 and 10 of the cycloconverter so as to tend to reduce to zero with time an error signal 19 obtained from a comparison between a required angular shaft position 18 and the actual shaft position 13, via a position transducer 14, processing algorithm 16 and a microcomputer 15. The error signal is processed in an algorithm 21 to produce an actuating signal 22 which modulates at a frequency  OMEGA the firing angles of the switch means 2, 3 and 4, such as thyristors or transistors, of the cycloconverter 1 via a firing unit 23 and changes the polarity of the phase-sequence of the modulated output of the cycloconverter in accordance with direction and change of shaft angular position required. In an alternative no motor shaft position measuring device is used and the motor shaft positioning is performed by applying to the motor the cycloconverter output of frequency OMEGA  which exists for a time interval  DELTA t related to the magnitude of angular rotation required. <IMAGE>

Title: Freqency reduction for input to processor used in feedforward distortion       correction
Inventor: KENINGTON PETER BLAKEBOROUGH
IPC: H03F1/32
Filed: 1992-05-05
Abstract: In a broadband amplifier (Fig. 2) an error signal is formed from the output by comparison in a subtractor 11 with the input and the error signal is combined in a coupler 17 with the amplifier output to reduce distortion. Automatic amplitude and phase control of the signals forming the error signal by means of components 24 and 25 in a multi-channel input and in the error signal by means of components 13 and 14 is provided.
